cam_mul array to Temperature and Tint and back

Hi guys,

is there some way how calculate Temperature and Tint value from camera white balance array and back?

I have
cam_mul = {1413, 1024, 2110, 1024};

and I know that it is for Temperature 3200 Kelvin.

For white balance I am using cameraWbCoeff = {1413/512, 1024/512, 2110/512, 1024/512}; and RAW after all changes is OK. But I need change required temperature like as in ACR or UFraw.

I am using Canon EOS-1DX

Thank you for advice

Best Regards Ladislav
